Check Digit Verification of cas no

The CAS Registry Mumber 34670-56-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,6,7 and 0 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34670-56:
(7*3)+(6*4)+(5*6)+(4*7)+(3*0)+(2*5)+(1*6)=119
119 % 10 = 9
So 34670-56-9 is a valid CAS Registry Number.

Obtaining symmetric and asymmetric bisphosphoramidates and bisphosphoramidothioates by a single step multicomponent reaction

, p. 634 - 642 (2021/02/12)

We present a new single-step multicomponent reaction strategy for the synthesis of symmetric and (novel) asymmetric bisphosphoramidate and bisphosphoramidothioate derivatives. Reactions proceed under routine experimental conditions, do not require the aid of any catalyst, and provide moderate yields after a short time. We synthesized 18 different compounds, 10 of them for the first time. The cytotoxic activity of our adducts was assessed by measuring their inhibitory capacity (IC50) against two different cell lines, the A549 (lung cancer cells) and the SW1353 (chondrosarcoma cells).
