Check Digit Verification of cas no
The CAS Registry Mumber 91074-06-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,7 and 4 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91074-06:
(7*9)+(6*1)+(5*0)+(4*7)+(3*4)+(2*0)+(1*6)=115
115 % 10 = 5
So 91074-06-5 is a valid CAS Registry Number.

Lactam Acetals: Part VIII - Further Investigation of Reactions with Araldehydes
Singh, Jujhar,Sardana, Vinod,Anand, Nitya
, p. 1079 - 1082 (2007/10/02)
o-Substituted araldehydes on reaction with 2,2-dimethoxy-1-methylpyrrolidine (1) first form dioxinopyrroles (2-6), which undergo facile hydrolysis to the (RR)-benzhydrols (7-11); the formation of 2-6 is particularly favoured with electron withdrawi
