Check Digit Verification of cas no

The CAS Registry Mumber 425431-08-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,2,5,4,3 and 1 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 425431-08:
(8*4)+(7*2)+(6*5)+(5*4)+(4*3)+(3*1)+(2*0)+(1*8)=119
119 % 10 = 9
So 425431-08-9 is a valid CAS Registry Number.

A strategy for the construction of caged diols using a photolabile protecting group

Lin, Weiying,Lawrence, David S.

, p. 2723 - 2726 (2007/10/03)

Caged analogues of biologically active compounds have received widespread attention as temporally and spatially controlled probes of cell-based processes. Recently, a coumarin-4-ylmethyl derivative has been used to cage carboxylates, sulfonates, carbamates, and phosphates. We describe herein a synthetic strategy that furnishes photosensitive caged diols and provides an entry into the protection/photodeprotection of functionality with modest leaving group abilities.
