Check Digit Verification of cas no

The CAS Registry Mumber 29700-19-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,7,0 and 0 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 29700-19:
(7*2)+(6*9)+(5*7)+(4*0)+(3*0)+(2*1)+(1*9)=114
114 % 10 = 4
So 29700-19-4 is a valid CAS Registry Number.

The Absolute Stereochemistry of Nebularine-Methanol Photoadduct. A Potential Transition-State Analog of Adenosine Deaminase

Shimazaki, Masami,Nakamura, Hikaru,Iitaka, Yoichi,Ohno, Masaji

, p. 3104 - 3112 (2007/10/02)

A stereoselective photoaddition of methanol to nebularine and 2',3',5'-tri-O-acetylnebularine was investigated.The absolute stereochemistry of the nebularine-methanol photoadduct (2a), a potential transition-state analog of adenosine deaminase, was determined to be 6(S) by X-ray analysis.The addition site of methanol on the purine ring was also chemically demonstrated to be at C(6).Keywords - photoaddition; nebularine; triacetylnebularine; transition-state analog; X-ray analysis; adenosine deaminase; enzyme inhibitor; coformycin; isocoformycin
